Looking at the current animations available in the marketplace 99% of the basic is already available so what would make a nice addition is A-B sync animation for say knife fights and take downs that usually requires renting studio time.
A nice change though is instead of a package covering a bunch of general animations it would be nice to have smaller matched sets based on a theme set up with ready to use blendspaces and animation BP’s. An 8-way movement package ready to plug and play that takes into account stops/starts turns has value over and above raw individual clips. A take down package as unique to a theme becomes and impulse purchase over buying an 80 dollar package just to get the few that are of use.
As a though/idea as a (cough cough) professional animator I do not buy mocap animations as to what I need but based on price and fair use licensing that I can make us in any project I wish. For the most part I already have most of anything where the character is grounded so anything in air or where character interact physically is something of interest to me.
A question I have though is who’s framework are you using? Is this a custom rigging solution necessary to to match with your animation sets or are you using Epic’s base rig?
A bonus idea.
Animations is not bound by any unique 3d space so a open marketplace to check out is over at daz3d.com. If you check out available animation packages, more so for the G3 framework there is very little, are not that good, and very expensive as compared to what is available on Epic’s marketplace. A little retargeting work to Genesis 3 and you could sell your product into a much larger, and focused, marketplace.
